Peter did not know of his black lineage in "Peter Griffin: Husband, Father...Brother?", after his son Chris started adapting other customs. After discovering he had a black ancestor at the Quahog Public Library he wasn't sure how to handle the information. He instantly became a part of the black community with help from his friend Cleveland Brown. He soon learns that his father-in-law, Carter Pewterschmidt's ancestors were Nate's owners. Peter received retributions from them, but Peter misuses the money by recreating the set of Pee-Wee's Playhouse in his own home, transforming it into Peter's Playhouse. While Peter is in a bathroom wondering what to do, Nate tells him to do what is right.
